App升级一般有两种方式: 第一种,是在App内部升级,自己写下载代码,一种是调到第三方浏览器中,让浏览器下载本应用升级(之前文章有讲过,链接地址:https://blog.youkuaiyun.com/wolfking0608/article/details/79619472)
下面重点介绍应用内部升级

}为了大家查看方便,没有使用分层处理. UpgradeDialog升级app内容的弹框,很好写,可以自己写一个,工具类可以照抄,但是逻辑代码仅给各位参考.
特别注意:
1. 这里适配了Android6.0以上的权限, 在清单文件中要注册一个内容提供者,否者你的权限申请不下来.
代码如下:rc_file_path.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths> 清单文件中要注册
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.FileProvider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/rc_file_path"/>
</provider>2. 可能你很久没有用服务了,服务也是需要注册的,否者你发现权限成功了,提示正在下载,就是通知栏里面就是没有下载的进度条,你可能怀疑是不是楼上这个教你的家伙,傻逼了? 其实是你自己没有注册服务,自己犯二了.
3. App下载进度条出来了,但是安装到快100%的时候,妈的,程序闪退了 就是安装不了
请你在复制的时候,查看一下,上面的工具类, 有一行我标了红色了 ,你程序的包名一定要填写上去!!!.因为你复制的是我Demo的包名.FileProvider.所以下载的时候发现不一样,能给你安装成功就他妈见鬼了.
4. 你下载App成功了,也进入下载页面了,麻痹的就是安装apk安装不上去,这是什么鬼? 检查了代码也没有错啊,自己发现自己找了半天原因还是没有找出来问题来? 怎么办?算了,我还是告诉你吧.你检查下,你的app和签名和你手机你的app的签名是否一致,两者的包名是否一致,如果不一致,是不会覆盖安装的,这个与你的版本没毛关系.所以你安装不上去
5.如果上面的4点你都做到了,代码也检查了,还是出现问题,那只能说明你人品太差了,自己好好检查和分析原因debug吧! 以上遇到的坑希望能够帮到你,如果能够帮到你,并节约你开发的时间,请给我点个赞,follow我一下,谢谢!
